A collaborative map of marine mammal sightings in and around the Thames. Also mapping the locations of 10 tracked seals (with playback and depth gauge), ZSL’s 2014 seal survey, gallery and other Thames Conservation projects.
A superior upgrade to the seal map I made in 2013. Graphic design by Jonny Burrows.
Powered by Leaflet.js, Mapbox, D3.js and the lovely nouislider.js. Data preparation in Quantum GIS. Slightly obsessively thorough user event tracking by Google Analytics.
